How could I resist? Look, I love that record and have nothing but great, great memories of my time with BLACK SABBATH . Tony was really busy but got his solos to me at the last minute as he promised and they are just fantastic. I think BLACK SABBATH fans will be over the moon when they hear what he's done. As for Roger and Ian , well, they just sound great on this song so it really did become 'Black Purple'. Personally, I love the irony of it all.
